DSM IV Criteria for attention-deficit/hyperactivity disorder
The Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) is the primary tool used by clinicians to diagnose attention-deficit/hyperactivity disorder (ADHD). The DSM-IV identifies three major subtypes, which are defined as follows:
Based on these criteria, three types of ADHD are identified:
- Predominantly inattentive type, where the symptoms include an inability to sustain attention, distractibility, and forgetfulness/carelessness.
- Predominantly hyperactive-impulsivity type, where the symptoms include excessive fidgeting, talking, and trouble enjoying leisure activities quietly.
- Combined type, which includes both inattentive and hyperactive-impulsive symptom.

Professor Judith Rapoport describes attempts to define cellular abnormalities in ADHD as something of a black hole, which may be due to the polygenic nature of the disorder.
